-ful Improvement in Adjustable Frames for Door Locks and Latches, of which the following is a specification.

My invention consists in the improved construction of a frame for containing the mechanism of a door lock or latch, and in improved means for making a lock or latch frame automatically adjustable to doors of] the said screws the frame of the lock or latch different thicknesses.

In the accompanying drawings z Figure 1 represents a front edge view of the lock or latch frame when applied to a comparatively thin door. applied to a thicker door.

Fig. 2 represents the same when Fig. 8 represents a top view of the lock or latch frame, a portion of the edge of the inner side plate being broken away on'the line 3, of Fig. 4, to show the construction of the frame. Fig. 4 represents a side view of the inner side plate of the frame. Fig. 5 represents a side view of the outer side plate. Figr6 represents a section taken on the line 6 6, of Fig. 3. Fig. 7 represents a section taken in the line 7 7, of Fig. 3. Fig. 8 represents an outer side View of the automatically adjusting rim plate. Fig. 9 represents a section taken on the line 9 9, of Fig. 8. Fig. 10 represents a forward end view of the tie-piece employed for securing the side plates together, and for bracing the front plate. Fig. 11 represents a side view of the tie-piece. Fig. 12 represents a section taken on the line- 12 12, of Fig. 7.

In the drawings, A represents the outer plate of the lockor latch frame, B the inner plate, and O the front plate, which extends from the plate A to the plate B, across the edge of the door. The side plates A and B are provided with the hand knobs a and b, respectively, and the front plate O is provided with the rectangular opening 0, adapted to receive the latch-bolt of the lock mechanism. The front plate O is preferably made integral with the outer plate A, and is pro vided with the inwardly directed flange d, having the notchopenings 6 c, which are adapted to receive the shanks of the screw studs ff, the heads of which serve to hold the inner plate B of the lock or latch frame firmly to the said flange d. The plates A and B are each provided with the inwardly projecting lugs g g, to which are secured the tie-piece D, which serves to hold the plates A and B in a rigidly fixed position relatively to each other, and to brace the front plate C under the action of the fastening screws lc 7c. The tie-piece D is secured to the lugs g g, by

means of the screws h h, and is provided with the forwardly projecting hollow arms 11 L, through the cavity of which the woodscrews 7c is are made to pass, and by means of may be properly secured to the door. In order to adapt this improved frame of rigid construction to doors of difierent thicknesses, I employ an automatically adjusted rim plate E, provided with a groove Z, which embraces the inwardly directed'flange m of the inner plate B, the spiral springs n n, serving to press the said rim plate E outwardly from the said flange until the lugs 0, integral therewith, bring up against the inner face of the heads g of the stop screws 10, as shown in Fig. 6.

The attachment of this improved rigid lock or latch frame to doors of different thicknesses, is shown in Figs. 1 and 2, the rim E automatically adjusting itself to the specific thickness of the door upon which the frame is placed, the rim plate being held against the side of th door by means of the concealed springs n 71., located in the groove Z of the rim plate, the rim plate E being cut away at its forward end as shown in Fig. 8, to provide the required space for the front plate O.

This improved lock or latch frame and its contained mechanism may be attached to the door in one piece by simply cutting a notch of suflicient depth in the stile of the door to receive the mechanism for operating the latch-bolt, the tie-piece D being made to rest against the bottom of the said notch, as indicated in Fig. 3. And by means of my improvement the frame may be attached to the door Without the employment of exposed screws which pass through either of the side plates.

I claim as my invention 1. A rigid lock or latch frame provided with an outer plate, and connected front plate extending across the edge ofthe door, I

and an inner plate secured to the front plate, a tie-piece which extends transversely between the outer and inner plates andis secured thereto, and extends forward to engagement with the front plate, the said front plate being perforated to receive the fastenmg screws, whereby the necessity for the employment of fastening screws through the side plates of the frame will be avoided.

2. A lock or latch frame rovided with an outer plate, and connected front plate extending across the edge of the door, and an inner late secured at its forward end to the end of the front plate, and a tie-piece which extends transversely between the outer and inner lates and is secured thereto, and extends forward to engagement with the front plate, and is adapted to hold the inner and outer lates firmly together.

3. n .a lock or latch frame, the combination of the outer plate, the front plate, and the inner plate, with a tie-piece adapted to hold the inner and outer plates firmly together, the said tie-piece being provided with the hollow arms extending to the rear side of the front plate, to receive the fastening screws, the said screws passin through the front late and through the ho low arms of the sai tie-piece.

4. A lock or latch frame comprising an outer plate provided with an inwardly extending lug, and a front plate extending across the edge of the door, and an inner plate secured at its forward end to the front plate, and having an inwardly extending lug, in combination with a tie-piece secured to the lugs of the inner and outer plates, and extending forward to engage the front plate, and constructed to receive the fasten ing screws, said screws passing through the front late and through the said tieiece.

5. X lock or latch frame provide with an outer plate, a front plate extending across the edge of the door, and an inner plate secured to the front plate, a tie piece secured to the said inner and outer plates, and extending transversely between the same, and

forward to engagement with the front plate,

6. A rigid lock or latch frame made of greater width than the thickness of the door to which it is to be ap lied, in combination with an automatical y adjustable rimplate, extending around the inner edge of the inner plate of the frame, whereby the said rigid lock or latch frame is made applicable to doors of different thicknesses.

7. An automatically adjustable rimlate in combination with a rigid lock or iatch frame, the said rim-plate extending around the inner edge of the inner plate of the frame, and bearing against the side of the stile of the door, whereby the said rigid frame is made applicable to doors of different thicknesses.

' 8. The combination of a rigid lock or latch frame comprising outer and inner plates, and a front plate extending across the edge of the door, with the automatically adjustable rim-plate extending around the inner edge of the inner plate of the frame, and cut away at its forward end to provide for the front plate.

9. The combination of a rigid lock or latch frame comprising outer and inner plates, and a front plate extending across the edge of the door, with the spring-actuated rim-plate extending around the inner edge of the inner plate of the frame, and means for limiting the forward movement of the rim-plate under the action of the springs.
